Justification:
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, it is known from fewer than five locations, and there is observed continuing decline in the extent and quality of its habitat and the number of mature individuals.

The species is endemic to central-eastern Sardinia around the Gulf of Orosei, occurring roughly between the valley of the Cedrino River and 40°N (in the province of Nuoro; Gasc 1997). It is found at altitudes between 100 and 1,400m asl.

Although the species has often been considered to be common, and even abundant, within suitable habitat (with recorded densities of as much as 300 animals per ha in some areas; Vosenek, van Rooy and Strijbosch 1987), it recently appears to have undergone a decline and has become more difficult to observe in its limited range (R. Lecis pers. comm.)

The species is found in humid rocky outcrops, limestone caves, crevices, and forested areas with a good growth of moss in the vicinity of streams. It reproduces through the direct development of a few terrestrial eggs.

The species is listed on Appendix II of the Bern Convention, and it is also listed on Annexes II and IV of the EU Habitats Directive. The species has been recorded from Parco Nazionale Gennargentu e Golfo di Orosei. Further research into the threats leading to the recent apparent declines in this species is needed.
